The offer of $25 off any canvas + free shipping has not changed, it's still on their home page. Your assumption that you could deduct another $25 off the already-reduced prices is what's wrong. I will fix it for you, it is misleading as you have posted it.

Houtex, free offer was there earlier and it got expired after the submission. Both screen-shots are right. 1st 1 was before the free offer expired and next one is for current deal. I didn't applied any codes here and both the screen shots are before checkout only.

This doesn't looks good making this as off the contest even after posting proof

Houtex, is this out of contest. If yes, could you please let me know one good reason about why this submission is out of contest. If your reason says about inaccuracy of submission, that is not the right. My screenshots shows about the proof of this submission before and after the expiry of the free 8*10 canvas
